Add new CleanMethod option.

As it was already mentioned several times, the new -Sc behavior in 3.1 is
great, but only when the package cache is not shared.

This option has two possible values : KeepInstalled and KeepCurrent
With KeepCurrent, -Sc will clean packages that are no longer available in
any sync db, rather than packages that are no longer in the local db. The
resulting behavior should be better for shared cache.
